Here are some animations I have been looking at in the initial stages of this project.
Firstly this one by DBLG, I really like the colour palette and how effectively a very serious message is conveyed in a positive light.
The movement in this next one, from frame to frame is charming. It would be really nice if we were to do our animation be hand and get this same feel.
This one can be seen as a loop here, A site which features only looping animations. If we were to hand draw our frames it would be much more realistic to keep it short, sweet and loopable.
